Packaged electronic system having selectively plated microwave absorbing cover

摘要

A packaged electronic system is formed of a base having a surface and a plurality of discrete electronic components disposed on the base surface. An absorbing cover reduces the electromagnetic resonance produced by the discrete electronic components disposed within the packaged system. The entire cover is molded using a composite electromagnetic wave-absorbing plastic material. The cover is selectively plated to satisfy the shielding requirements of the packaged system.
